• What is the cause and solution for SAP error message AD345 - Table & (different key length in client &) ?

  The SAP error message AD345 indicates that there is a mismatch in the key length of a table between the client and the database. This typically occurs when there are inconsistencies in the data dictionary or when the table structure has been modified in a way that is not consistent across different clients or systems.
  Cause:
  
  Inconsistent Table Definitions: The table definition in the database does not match the definition in the SAP data dictionary (DDIC) for the specific client.
  Transport Issues: If changes to the table structure were transported from one system to another (e.g., from development to production), and the transport was not executed correctly, it could lead to discrepancies.
  Client-Specific Customizations: If a table has been customized in one client but not in others, it can lead to different key lengths.
  Database Changes: Manual changes made directly in the database (outside of SAP) can also lead to inconsistencies.
  
  Solution:
  
  Check Table Definition: Use transaction SE11 to check the table definition in the data dictionary. Ensure that the key length matches what is expected.
  Compare Clients: If you have multiple clients, compare the table definitions across clients to identify discrepancies.
  Transport Corrections: If the issue arose from a transport, ensure that the transport was correctly executed and that all necessary objects were included.
  Re-Generate Table: If necessary, you can regenerate the table using transaction SE14 (Database Utility) to synchronize the database structure with the data dictionary.
  Check for Manual Changes: Investigate if any manual changes were made to the database that could have caused the inconsistency. If so, revert those changes or adjust the DDIC accordingly.
  Consult SAP Notes: Check the SAP Support Portal for any relevant SAP Notes that might address this specific error or provide guidance on resolving it.
